Import Tips

Provide frequency response and hum reduction specifications to distinguish from general-purpose transformers

Ensure nameplate clearly states 1 kVA capacity; customs audits focus on power rating accuracy

Avoid packaging with audio cables that could trigger 'set' classification under different rules
